my mom had treatment years ago- which wasn't the best (i was too young and only really recall seeing 3 giant holes in her leg).
I'd ask you're physician about the varicose veins though, it could be a venous valve problem that could lead to some serious problems later.. (Ambulatory venous hypertension & venous ulcers)
obviously exercise and walking/running are good ways to help venous blood flow,
but those with varicose veins have less effective auxiliary pumping mechanism generated by the proximal skeletal muscle. ((sorry, have a final on cardiovascular system coming up.. have to know about it)).
not really sure about treatments, but definitely should not take them lightly. laser may not be too bad?
